Default Dobeck gen IV fuel controller

getting it dialed in with help from Red Vic. bike feels stronger + runs better. its good to be able to SEE your REAL fuel ratio on the gauge, exactly what i need on a mildly modified Hammer. not looking for ultimate power + will never do cams or open the engine unless it breaks. install was not bad, i work slow + follow the instructions!

it is a lovely device isn't it? I am very pleased with mine. My bike is now quicker, faster idles better, and runs cooler- and still gives 40+ mpg.

Is there some reason it won't work with cams?

I think he's just saying he's not going to do cams, not interested. I'm sure it will work with cams.
Ordered mine last week, they said 10-14 days before shipping (?) Maybe they build them as they are ordered, I don't know. I'm interested in putting it in diagnostic mode as soon as I install it to see where I have been running. Then putting it control.

Default Dobeck + cams

the gen IV will work period! what most say is if you do cams or upsize your engine to get the "most" out of it on a DYNO tune the adjustability of a power commander is best. with the Dobeck or VFC gen IV you set the fuel ratios you want, there is no ability to alter timing. so if you put thousands into your engine another thousand for a fuel tuner + dyno to get the best performance is preferred if you got the $$$$$. that little xtra is costly but it depends on what you want + are willing to spend

rodhotter-when you get a chance can you post what settings you used that way i can get a good starting point for mine especially on the switching points.

I sent you a PM with some detailed instructions with settings for each mode. Only Mode one (Green Mode) might be different than the number in the directions when you first set up the programmer.

The others you can start with the numbers provided as they are a pretty solid starting point and you should not have to change them much. Just don't go to rich your acceleration modes. If you are going down into the lower to even mid 12's on your Red acceleration mode you are going to be way to rich. The Green/Blue acceleration mode you will enter a number in the low 12's but remember that one is not an air/fuel ratio it is just adding or subjecting fuel.

The only air/fuel ratio settings you will have will be your Yellow cruise mode and your Red acceleration mode.

This programmer will also work fine with cams.

One note about the Dobeck programmer. When you are cruising along under a light throttle cruise you may switch from the closed loop yellow cruise program into the green open loop light cruise program, this is not an issue so don't try tweaking the switch points trying to force it stay in the closed loop yellow mode program.

The green open loop program is for idle and light cruise.

Here are the numbers I am running:

Green- 11.7
Yellow- 14.2
Red- 12.9
Blue/Green- 14.5
Blue/Yellow- 11.0
Blue/Red- 12.0

Stage 1 filter

I have been setting it to hold approx 14 on light cruise open loop (green only) 3rd, 4th, 5th gears. and 14 in closed loop (blue yellow).
